' i-This invention relates to yniea'nsfor lselectively operati-ngvalves.V The invention iind's an yapplication in connection with valves pertaining tothe chainhersot` a1 multiple com- 51: gartinent vehicle tank.'

The object is to provide simple, eiiiective and:4 convenient mechanism, and' more particularly mechanismvin which one of two shafts extending lengthwise of a series' of f mtvalve connections serves to open a selectedA Valve, whilefthe other ofsaid shafts is operab'le forpurpo'sefofselection. f

An index, not'sho'wn, may be pro-v f vided in connectioiiwth thshand Wheel'to assist' the operator determining the'piop'er through the tubular shaft13.

These' 'connectors have projecting' lugs 24g-winch projecciniiiiierent angul-an relations; f The conliector-V c'o aria'nge dito abut'ltlie leiffeiisf, and"y the 24* are adapt'ed to align-l enei at; time the actuatinglugs or elements 21 of ltli'efnotti-1- 2,300, and the Ful'-v lease 26 is preferably provided in connection with the? handle 19to bring about closing of the open valve or valves in event of fire at the rear end of the tank, this thermal release being similarto that of the Emmich patent. As in the Fullerl & Betts patent, a so-called cab-release 27 is provided at the forward portion of the actuating shaft 10for turning the latter to bring about release of an opened valve in case it should be necessary to effect such closing lfrom the forward end of the tank. Such kturning movement ,rocks the actuating lugs 21, so that the connector collar 22 of thev valve Which Was opened is free to move forward thereby permitting the valve to `close. In thepresent construction, hovvever, the shaft 10 does not have to be disconnectediivith the opera-ting means at the rear end for the purpose of thisy releasing operation, since the shaft 10 does not have to move forward to permit the release of the opened valve. Accordingly, a permanently' connected swivel connection is provided between the rear end of the shaft 10 and the crank arm 17. v

While the preferred form ofthe invention has been described in detail, it will be understood that numerous other arrangements may be devised Without departing from the essential plan. s 2

ln connect-ion' with the cab-release, or front-,end release, it may be noted that a spring 28 normally holds an arm 29 on Ya rotatable sleeve 3,0,livith which the front end of the actuating shaft 10 is slidably connected, against a stop 31, sothat the actuating lugs 21, which are all in line, are kept in positions which enable them to Lact upon the lugs 24 when the actuating shaft is moved rearward. The sleeve 30 and thereby the lshaft 10 can Vbe turned by a suitable handle or 3ink 31 connected to the arm 29, so as to rock the actuating lugs 21 to positions in which none of them will engage the lugs 24.

The shafts 9V and 10 are journaled in suitable brackets 33 on top of the tank, the levers and 8 being likewise mounted on these brackets. Y f f i l claim: 1.
